This is really, really charming along with a great concept! The first try of each battle does feel like a game of chance because of not knowing the opponent's wheel, but that's not a problem due to being able to retry the battle without having to go back to the start. Said battles do end up being easy to win after the first attempt though as you can then mostly or fully equip the element with the highest likelyhood of winning and just try until you get lucky.
